KEYBOARD FOR TYPE-SETTING MACHlNES.

SPECIFICATION forming part of Letters Patent No. 719,375, dated January 27, 1903.

Application filed December 21, 1901. Serial No. 86,757- (No model.)

To aZZ whom it may concern:

Be it known that I, OoLoMAN RoziiR, a subject of the Emperor of Austria-Hungary, residing at Nuremberg, Germany, have invented a new and usefulKeyboard Device for Type- Setting Machines, of which the following isa specification.

This invention relates to an improved keyboard for type-setting machines of all kinds and other similar apparatus, the characteristic feature of which device consists in the fact that the operations or manipulations to be effected by means of the said keyboard can only take place after the key which has been acted upon has been released. The advantage of this arrangement is that when the keyboard is employed with linotype-machines, for example, the same letter is not repeatedly set when the key which has been struck is notreleasedquicklyenough. If myimproved keyboard device is employed in conjunction with a punching appliance for the registering-strips for automatically-acting composing-machines, for instance, owing to the fact that the movement of the apparatus required in order to efifect the punching operation is only commenced or prepared for by the de-. pression of the key, the said movement taking place only when the key again rises, the same punching effect cannot be repeatedly produced by one and the same depression of a key, however long such depression may be continued.

A constructional form of my improved keyboard device is represented in the aocompanying drawings, in which Figure 1 is a sectional view through a keyboard embodying this invention in the condition of repose, and Figs. 2, 3, and 4 are sectional views of the same in the different positions.

When depressed, each key 1 acts upon an anchor-lever 3, rotatably mounted upon a shaft 2. This lever is maintained raised by means of a spring at. In the plane of each of these anchor-levers is rotatably mounted upon a shaft 5 athree-toothed locking-disk 6, which is submitted to the influence of a spring 7, which bears against the corresponding rod 9. This rod 9 is also acted upon by a spring 10, in opposition to the action of the spring 7 and tending to draw the rod 9 toward a rocking lever 11, the rods 9, which are provided with noses 12, being pivoted to the extremities of these levers 11. So long as the locking-disk 6 is retained in the position of rest (shown in Fig. 1) by the nose or hook 14. of the lever 3 resting upon the tooth 13 the influence of the spring 7 preponderates in such a manner that the arm or rod 9, with its nose 12, is held out of the path of a rail 15, which is fixed upon a lever-frame 16, which latter is maintained constantly oscillating upon an axis 18 by means of a continuously-rotating shaft 17. This is stillthe case when the key 1, and with it the anchor-lever 3, is depressed, Fig. 2, as the disk 6 merely rotates slightly until its tooth 19 comes into contact with the arm 20 of the lever 3. When the key 1 is released, Fig. 3, the

spring 4.- raises the lever 3. The locking-disk is thus released and continues to rotate under the influence of the spring 7 until its tooth l3 bears against the transverse ledge 21, whereupon the tension of the spring 7 is diminished to such an extent that the spring 10 is able to draw the arm 9, with its nose 12, into the path of the rail 15. \Vhen this latter next descends, it takes with it the arm 9 by engagement with the nose 12, Fig. 4. The extremity of the lever 11 then engages with the tooth 22 of the disk 6 and causes it to resume its initial position, so that the nose 14 is again in front of the tooth 13, and at the end of the ascending movement of the rail 15 the arm 9 is withdrawn from the path of the said rail by means of the spring 7, which is again placed in tension. Each arm takes with it in its downward movement one of the levers 11 or actuates by means of a pin 23 a lever 24 or other part by means of which the displacements or manipulations of the device or ma chine which is for the time being connected up with the keyboard apparatus is efiected.

I claim- 1. In an apparatus of the character described, the combination with an actuatinglever, power devices, and a key, of means controlled by an adjustment of the key for connecting said lever and power devices after the key has been restored to its normal position.

2. In an apparatus of the character described, the combination of an actuating-lever, power devices, means adapted to connect said lever and power devices, a locking device normally holding said connecting means in inactive position, a key adapted to be adjusted to withdraw the locking device from engagement with said connecting means, and means for preventing connection of the lever and power devices until the key is restored to its normal position.

3. In an apparatus of 'the character described, the combination of an actuating-lever, powerdevices, means adapted to connect said lever and power devices, a locking device normally holding said connecting means in inactive position, a key adapted to be adjusted to withdraw the locking device from engagement with said connecting means, and a stop controlled by movement of the key for preventing connection of the lever and power devices until the key is restored to its normal position.

4C. In an apparatus of the character described, the combination of an actuating-lever, power devices, spring-actuated means adapted to connect said lever and power devices, means for normally holding said connecting means in inactive position, an ad justable key, and means controlled by said key for intermittingly releasing and engaging said connecting means during each movement of the key, whereby the lever and power devices will not be connected until the movement of the key has been completed and it is in its normal, inactive, position.

5. In an apparatus of the character described, the combination of an actuating-lever, power devices, means adapted to connect said lever and power devices, a locking device normally holding said connecting means in inactive position, a stop for said connecting means, and an adjustable key adapted at each operation to successively release said lock and move said stop to and from engagement with said connecting means, whereby the lever and power devices will not be connected until the movement of the key is completed.

6. In an apparatus of the character described, the combination of an actuating-lever, power devices, a pivotally-mounted rod adapted to connect said lever and power devices, a revoluble disk mounted at one side of and connected with said rod, a key-lever normally engaging said disk and holding the connecting-rod in an inactive position, a key con nected with and adapted when depressed to disengage the key-lever from said disk, to perunit the connecting-rod to move toward its operative position, and a stop adapted to be adjusted into position to engage said disk as the key is depressed and before the connecting-rod reaches its operative position to prevent connection of the lever and power devices until the key is restored to its normal, inactive position.

7. In an apparatus of the character described, the combination of an actuating-la ver, power devices, a swinging rod adapted to connect said lever and power devices, aspring acting to move said rod into operative position, a key-lever having two stops and adapted to hold the connecting-rod out of operative position, and a key connected with said lever,

acting to move said rod into operative position, a key-lever, and two stops connected with and adapted to be adjusted by the movement of the swinging rod into and from engagement with the keylever during each movement of said lever, for the purpose set forth.
